Unregistering DLLs

Introduction:

What are DLL files?

DLLs are dynamically linked library files. DLL file contains a list of certain functions that can be used by various applications. Spool32.dll is a great example of how the things work: that file is used by various programs for print control within Windows 95 and Windows 98.

Why is it important to unregister malicious DLLs?

DLLs may contain information essential for a computer to function properly. Malicious programs may corrupt regular DLL files or they may install new DLLs instead of normal ones.

Deleting DLLs is a risky deal since it can affect computers performance and functionality of many applications. If a malicious DLL is somehow used by a regular application and the DLL file is removed, the application won't work normally even if the deleted DLL is not needed for a program to function. This is why you have to unregister DLLs before deleting them.

How to unregister malicious DLL files?

a) Open Command Prompt window
Click the "Start" button and select "Run" option. Type "cmd" into the "Open" field and click the "OK" button.

b) Unregister malicious DLL file
Type "regsvr32 /u filename.dll" into the Comand Prompt window and click "Enter". "Filename.dll" should be the name of DLL file you want to unregister

The ordinal 120 could not be located in the dynamic link library iertutil.dll


iertutil.dll is a dynamic link library used by Internet Explorer. Ordinal 120 refers to something inside the dynamic link library. These errors typically occur when the file is corrupt or there is a version mismatch (eg. IE 9 using iertutil.dll from IE 8). A reinstall of IE should fix this problem

Acer Aspire One Netbook D260A.Windows XP not booting. Message Reads Windows could not start because the following file is missing or corrupt. Windows Root System 32 Hal dll No recovery disc or USB recovery available. Step by step how to Fix? Help appreciated. Thanks


Sometimes you can get the needed .dll file online, and manually place it on that drive, of course in the correct directory.To do this, you need a functioning computer and you hook up the hard drive with the problem VIA USB. You can get USB Hard drive adapters from most retailers.

You may want to extract all data before you do anything, just in case. Have you been doing backups????

Usually, you reinstall the OS to resolve this issue, but without disks, not so easy to do.
